ments in Tire-Shoes, 'of which the following is a specification.

This invention relates to an improvement in shoes for tires, and moreparticularly to a structurerwhich is adapted to be fitted over a Wheeland tire when the motor vehicle or other machine of which the wheel is apart is'traveling in the mud or is set in the mud in such a way that thetraction Wheels slip without giving the proper driving power.

An object of my invention is to provide a device as described which canbe attached to the wheel and tire to lbe used in traveling through mud,or which may be fitted in placeafter the vehicle 'has stopped and evenwhen the wheel is in the mud up to the axle,

the parts being so arranged that the device may even be fitted in placeby an operator standing upon the running board ot the vehicle and thesecuring means may be manipulated with one hand.

A further object lies in so constructing the device that severalindividual shoes are mounted at various lpoints around the periphery ofthe tire to thus distribute the driving strain and each otthe severalshoes will be given support by being braced from the remaining slices.-y

A still further object is to so construct the securing means that thedevice ma)7 be fitted to be used upon wheels and, tires of various sizesand when not in use may be toldedto occupy a comparatively small compassso that it canbe packed or stored under a seat or inA a tool box and canthus be conveniently carried.

W ith the abone and other objects in View, mv invcntionfconsists incertain novel features' of construction and combinations of parts whichwjill be hereinafter set forth in connection with the drawings and thenmore particularly pointed out in the claims.

In the drawings, Figure 1 is a view in side elevation of a wheel andtire havingr the device of my invention fitted in place thereon. Fig. 2is a transverse sectional view through the wheel rim and the tireshowing in greater detail one ol the mud slices. Fig'.

3 is a plan view of one of the shoes to better '.villustrate thearrangement of the cleats thereon. Fig. a is an enlarged detail viewshowing the means for tightening the device in the operative relationand by which the;

adjustment for the various sizes off tires is secured.

The three mud shoes 1,'2 and 3 are each ot' substantially the same form,and asis better shown in Fig. 2,' these mud shoes are shaped to be incross section substantially U- shaped so that they can be readily fittedover and removed from the tire and wheel. The tire 4 andthe wheel 5 areot' the usual construction, the wheel being so built that the hub Gextends outwardly slightly from the plane of the outer sideiof the tireand rim,

' as in the usual wheels .as nowbuilt into au'- tomobile or motorvehicle constructions. The substantially U-shaped portion of the membersl, 2 and 3 is constructed to have -the two arms thereof ot'substantially the same length and made suii'iciently long that it willextend down and adjacent to the side edges of the rim, and onev of thesearms of each of the members has the bearing ears 7, S, and 9, as bettershown in F ig. 1.

Links 10, 11, and 1 2 are connected pivotally with the bearing ear 7, 8and 9, and at their free ends are provided vwith open loops or eyes.Brace arms 13 and 14k are hingedly connected with the bearing ear 7 andextend to ea'ch side in a spread relation, and similar brace arms 15 and16 are connected with the bearing ears 8 and and at their free ends are.hingedly connected ith the free ends of the arms 13 and 1l respectively.It is preferable that stop lugs 17 and 18 be provided upon the bracearms so that the swinging movement thereofl in the opening relation willbe limited to hold the two connected arms of each pair in ahnement whenbrought to. their full open position.

A iexibleeable 19 is connected at its ends with the ends of the links 1land 12 and in its central portion is looped as shown in Fig. 1. and achain 20. having open links, is connected with the free end of the linkv10.
